## Exercise 9.5

Using the given data file (Ex9_5_NLR) in Matlab
format or text format, which contains
two predictors *x*_{1} and *x*_{2} and
predictand *y* data (80 observations), develop a nonlinear
regression model of *y* as a function of *x*_{1} and
*x*_{2}. Briefly describe the approach taken (e.g. MLP,
SVR, ensemble, etc.). Forecast *y*_{test} using the new
test predictor data *x*_{1test} and
*x*_{2test} provided.
